Thanks for the summary ?We decided to replace our 2004 Burgman 400 (non ABS) with a gently used 2016 Burgman 400 - ABS model last year. Picking a 2016 model was deliberate for three reasons. 1) price ... older years and generations usually sell for less of course; 2) the diminished under seat cargo space was a game stopper on the > 2016's and; 3) parts availability are plentiful for the 2016 (same parts for model years 2007-2016) versus something newer with fewer on-road units.
The slightly lighter weight and "thinner" styling cues of the 2017+ models weren't nearly enough to sway us towards a newer one.
For the record, we found little difference between the 2004 and 2016 models. They're both comfortable, economical, decent handling scooters that did/do everything we asked of them. The newer one is made even better by sporting the GIVI Airflow windscreen, handguards, Grip Puppies over OEM heated grips, ABS brakes (OEM), GIVI E22 side cases and a GIVI V46 rear top case painted to match the scoot. Tidbit = more overall cargo capacity than a Honda Gold Wing.
